In competitive gaming, footsteps, reloads, and directional audio cues mostly live in the mid and high-mid range — exactly where a quad equalizer can bring them forward.
Try a small cut around 60Hz to reduce explosion rumble that can mask other in-game sounds, a slight boost around 2.5kHz for footstep and cue clarity, and a touch of boost at 8kHz for overall crispness. Keep changes modest — a few dB goes a long way for gaming audio.
Gaming headsets often already emphasize the high-mid range for positional cues, so smaller EQ adjustments are usually enough. Desktop speakers in a real room may need a slightly stronger cut at 60Hz to prevent bass buildup from masking footstep detail.
